[0042] Reference Figure 6As shown, specifically, the tops of the two rubber strips 13 are fixedly connected with second rotating rings 14 , and the interiors of the two second rotating rings 14 are movably connected with pipe covers 15 , so that the openings of the water pipes 11 can be quickly closed by the pipe covers 15 .

[0043] Reference Figure 2 As shown, specifically, a rotating shaft 16 is fixedly connected inside the right side of the external frame 1 , a supporting plate 17 is fixedly connected to the right side of the top of the external frame 1 , and a supporting fixing clamping plate 19 is kept vertical to the liquid inlet 23 .

[0044] Reference Figure 4 As shown, specifically, a sleeve rod 18 is movably connected to the outside of the rotating shaft 16, a fixed clamp 19 is fixedly connected to the top of the sleeve rod 18, a centralizing pipe 20 is fixedly connected inside the fixed clamp 19, an exhaust pipe 21 is fixedly connected to the top of the centralizing pipe 20, two fans 22 are fixedly connected inside the centralizing pipe 20, and the two fans 22 are symmetrically distributed inside the centralizing pipe 20.

[0046] Working principle of the utility model: when transporting formaldehyde in a tank container, the liquid tank 3 can be stably fixed on the train through the connecting plate 2 and the external frame 1. During the transportation, the external temperature is continuously detected through the two temperature sensors 7 on the top of the fixing plate 4. When it is detected that the external temperature is too high, the block 5 cools the outer wall of the liquid tank 3 through the refrigeration pipe 9 between the liquid tank 3 and the outer cover pipe 10. At the same time, the pipe cover 15 on the top water pipe 11 can be opened, and water is put into the cavity between the liquid tank 3 and the outer cover pipe 10 through the water pipe 11. When the water is filled, the pipe cover 15 is re-fixed on the top of the water pipe 11 through the rubber strip 13. The fixing plate 4 and the inner part of the outer cover tube 10 are kept sealed to isolate the external temperature to a certain extent, so that the methanol inside the liquid tank 3 is kept at a suitable temperature and the vaporization of methanol due to excessive temperature is reduced.

The concentrating pipe 20 can be fixed above the liquid inlet 23 through the sleeve rod 18 and the support plate 17. During the rotation of the two fans 22, the gas inside the liquid tank 3 is transported to one side through the concentrating pipe 20 and the exhaust pipe 21 to avoid the vaporized methanol gas from staying near the liquid inlet 23, thereby improving the safety of methanol output.
